Armoured One
Armoured Ones 23 Mil. Shooter Attack Film was invented to retrofit into your existing windows to slow down or stop an active shooter, by slowing down an active shooter after they have shot the glass and film. Many companies claim to have window film that does this, but they have not tested to the FILTI Shooter Attack Certification level. Moreover, there is no film in the world that will make existing 1/4 inch glass bullet proof or bullet resistant through single layer application.
